description: This profile sets minimum expectations for the Specimen resource to record, search, and fetch \"substances being sampled or tested. (e.g., nasopharyngeal swab, whole blood, serum, urine, wound swab)\" associated with a patient to promote interoperability and adoption through common implementation. It identifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains the way the elements are used when using this profile. It provides the floor for standards development for specific use cases. package_name: rs/hl7.fhir.us.core derivation: constraint name: USCoreSpecimenProfile type: Specimen elements: type: short: (USCDI) Kind of material that forms the specimen binding: {strength: extensible, valueSet: 'http://cts.nlm.nih.gov/fhir/ValueSet/2.16.840.1.113762.1.4.1099.54'} mustSupport: true index: 0 subject: type: Reference short: (USCDI) The patient where the specimen came from. mustSupport: true refers: ['http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient'] index: 1 package_version: 6.1.0 class: profile kind: resource url: http://hl7.org/fhir/us/core/StructureDefinition/us-core-specimen base: http://hl7.org/fhir/StructureDefinition/Specimen version: 6.1.0 required: [type]
